Of the desire of souls in Purgatory to be wholly cleansed of the stains of their sins. The wisdom of God who suddenly hides their faults from these souls.
The soul was created as well conditioned as it is capable of being for reaching perfection if it live as God has ordained and do not foul itself with any stain of sin. But having fouled itself by original sin, it loses its gifts and graces and lies dead, nor can it rise again save by God's means. And when God, by baptism, has raised it from the dead, it is still prone to evil, inclining and being led to actual sin unless it resist. And thus it dies again.
Then God by another special grace raises it again, yet it stays so sullied and so turned to self that all the divine workings of which we have spoken are needed to recall it to its first state in which God created it; without them it could never get back thither. And when the soul finds itself on the road back to its first state, its need to be transformed in God kindles in it a fire so great that this is its Purgatory. Not that it can look upon this as Purgatory, but its instinct to God, aflame and thwarted, makes Purgatory.
A last act of love is done by God without help from man. So many hidden imperfections are in the soul that, did it see them, it would live in despair. But in the state of which we have spoken they are all burnt away, and only when they have gone does God shew them to the soul, so that it may see that divine working which kindles the fire of love in which its imperfections have been burnt away.
